Even though Doug Benson once told us, “The TSA, for the most part, does not care about marijuana,” the administration does care about grenades — or anything shaped like a grenade.

“Anything resembling a grenade is prohibited in both carry-on and checked baggage,” the TSA wrote on its Instagram this week. “Especially if it’s a grenade shaped grinder with marijuana inside. This grenade-shaped grinder was discovered in a carry-on bag at Sacramento International Airport (SMF).”

The primary purpose of TSA screenings at U.S. airports is safety and security, but if TSA agents find something that violates federal law, they will direct the situation to law enforcement. Here’s what the TSA wrote on its Insta when agents discovered the cannabis flower in the fake-bottom juice can in Nashville:

“TSA’s screening procedures, which are governed by federal law, are focused on security and are designed to detect potential threats to aviation and passengers. As has always been the case, if during the security screening procedures an officer discovers an item that may violate federal law, TSA refers the matter to law enforcement. This was the case after our officers discovered marijuana in the false bottom of a can of tomato juice that was located in a checked bag at the #Nashville (#BNA) International Airport.”
